The windows console will use these Esc-O sequences for arrow keys when in
"application mode", otherwise it uses Esce-[ ("normal mode").  Note
that some of the function keys also use the Esc-O prefix, while on an
ANSI terminal that has multiple character sets it would switch to the
third shift layer IIRC.

I would interpret that to mean the display is graphics capable, but the
selected frame still runs on a terminal emulation.  I think that might
happen if you connect from a terminal based emacsclient to an emacs
server that runs on a graphical display.
